When Makoto had Tom build the ship, he had emphasized that the soundproofing of the rooms had to be good enough.
Tom clearly hadn't forgotten and had focused on this aspect, telling Makoto when handing over the ship that [Soundproof Dials] had been installed in the interior walls of each room.
These were special shells from Skypiea that could absorb sound.
That night, Makoto tested it and found it was indeed good.
But the problem was… it couldn't withstand the high spirits of the women that night.
Especially Utaha, the Aizono sisters, and the others who had explicitly received guarantees from Makoto about new power-ups.
It wasn't just about not restraining themselves... they were literally screaming for dear life.
Especially Yotsuba, who had just received the Magma-Magma Fruit… previously, when she was with the other women, she had been quite restrained, basically covering her mouth the whole time.
But tonight, she seemed to have directly switched careers to become a soprano singer. If Vitas heard those high notes, he'd have to enroll in day school.
"Yotsuba, don't use your ability at a time like this."
Feeling the burning sensation coming from there, Makoto reminded her.
Although he could regenerate limbs by drinking blood and now had Armament Haki for defense, magma was simply too hot... the experience wasn't good.
"Ah, sorry Makoto-kun. I'll practice more in the future."
Yotsuba wiped the saliva from the corner of her mouth and apologized.
Makoto: "..."
'Good grief. What would Akainu think if he knew you were using the Magma-Magma Fruit for this?'
For the women who hadn't yet been intimate with Makoto, that day was definitely a sleepless night.
'Could they let people sleep at this time of night?'
Nino kicked the wall in anger, then walked out of her room wanting to get some fresh air to relieve the heat inside her.
But as soon as she came out, Nino discovered something.
The other sisters, even all the women who hadn't been intimate with Makoto, and the members of the MILF Group, were all outside getting some air.
For a moment, the atmosphere was extremely awkward.
Everyone looked at each other, no one speaking.
Just then, they suddenly heard a shouting that sounded like crying or screaming.
Everyone's expression changed.
They were certainly familiar with this kind of sound… after all, it came from Makoto's room every night.
But the problem was, they hadn't heard this particular voice before.
And it was too young, clearly coming from a little girl who hadn't entered her voice change yet.
"It sounds like... Nayuta's room."
Kokoro blinked and said.
Ever since moving onto the Otherworlder-Go, she and Kotonoha also had their own private rooms, no longer living together like before.
"A-a-are children this precocious these days?"
Kaguya's face turned bright red.
Her understanding of such matters had been limited before, but after being 'educated' by Makoto for over two months, she now knew what that kind of thing represented.
At the same time, she couldn't help but wonder… was that kind of thing really that enjoyable?
But regardless, for Nayuta, a girl of about second-grade elementary school age, to make such sounds, wasn't it a bit too early?
Nayuta's intimidating power was, in some ways, even greater than Makoto's.
Apart from Makoto and Kokoro, basically no one dared to talk to her.
Therefore, regarding Nayuta's behavior, the women initially chose to ignore it. After all, the little girl was entitled to her privacy.
But the problem was—
Over an hour passed, and Nayuta's sounds still hadn't stopped.
The women outside looked at each other.
'Seriously? Was this elementary school girl that fierce?'
'Aren't you afraid of passing out?'
"Maybe... we should remind her? She's too young... it's not good to be addicted to this."
Hayasaka Nao couldn't help but suggest.
"Alright, then Chika-nee should go!"
Moeha raised her hand to propose.
"Huh? Why me?"
Chika jumped in fright.
Moeha said seriously, "Chika-nee is more familiar with her, right?"
After all, Chika served as Prime Minister of Nishikawa Country in the real world and frequently reported work to Makoto.
And since Nayuta basically stuck to Makoto when not in school, over time, the two had become relatively familiar… even if they hadn't spoken many words.
The others were also afraid of Nayuta and didn't dare to disturb her, so they chimed in: "You go, Chika!"
With no other choice, Chika went to Nayuta's door, took a deep breath, and knocked.
"Um... you should probably do that kind of thing less often. It's bad for your health."
There was silence in the room for a moment.
Then, Nayuta's voice came from behind the door, trembling slightly as if she were trying hard to hold back.
"Th-that won't do... o-once we reach Fish-Man Island, I won't be able to experience this feeling."
Chika was dumbfounded.
'What did she mean?'
'What did she mean by 'once we reach Fish-Man Island, I won't be able to experience this feeling'?'
'Your clam is your own. Can't you grind it whenever you want?'
Chika finally returned.
But the sounds from Nayuta's room did not stop.
"Chika-nee, Nayuta didn't listen to you?"
Moeha came over and asked.
Chika remained silent. She was still thinking about what Nayuta had meant by those words, 'So what did she mean by 'once we reach Fish-Man Island, I won't be able to experience this feeling'?'
The others didn't press further either.
Because they weren't surprised by this outcome.
After all, Nayuta listened to no one except Makoto.
They just hoped that child wouldn't indulge too much and hurt her body.
Sayuri and the other mothers were quite maternal and felt they should find an opportunity to talk to Makoto later, asking him to remind the child not to overindulge.
But the immediate problem was—
How were they supposed to sleep tonight?
Not only were Yotsuba and the Aizono sisters in high spirits, but now Nayuta had been added to the mix.
"Hey, maybe we can buy better electric toys when we get to Fish-Man Island."
Someone muttered quietly.
"Erina-sama, I have a good idea."
Noticing Erina's increasingly gloomy expression, Hisako's eyes lit up. She approached her mistress and whispered a few words in her ear.
Erina blinked as she listened to her little secretary's quiet words.
Then, her face grew redder and redder.
"Wh-what nonsense are you saying!!"
Erina lowered her voice and scolded in a volume only the two of them could hear.
But Hisako just looked at her with a smile, her eyes saying 'Stop pretending, you know what you want'.
Erina opened her mouth to retort, but in the end, nothing came out.
She just turned her face away.
But her ears, red to the tips, betrayed her.
